How many 3 digit numbers can you make using these numbers: 4,2,9 (numbers can be reapeated)

bogdanovich [222]

Answer:

You can make 27 different 3 digit numbers

Step-by-step explanation:

Since we can use 3 different numbers this means that each of the 3 digits can be one of the 3 numbers (4,2,9). This means that there are 3 different values for the first digit, 3 different values for the second digit, and 3 different values for the third digit, which mean that we can make 3 x 3 x 3 different 3 digit numbers (we took the number of possible values for each digit and multiplied them together.

3 x 3 x 3 = 27

How many ways can an employer send 3 employees to a job fair if she has 11 employees?

algol13

We have to find the number of ways an employer send 3 employees to a job fair if she has 11 employees.

This is the problem from combination.

The formula for combination is given by

$^nC_r= \frac{n!}{r!(n-r)!}$

Here, n= 11, r= 3

Therefore, total number of ways is given by

$^{11}C_3= \frac{11!}{3!(11-3)!}\\
\\
=\frac{11!}{3!8!}\\
\\
=\frac{8!\times 9 \times 10 \times 11}{3!8!}\\
\\
=\frac{9 \times 10 \times 11}{6}\\
\\
=165$

A is the correct option.

A soccer team made 76 penalty shots out of 100.Which ratio represents successful penalty shots to missed penalty shots?

almond37 [142]

Sense we are wanting to find <u>how many were miss</u>, then, we are practically going to subtract the following:

$\boxed{76-100}= \ \left[\begin{array}{ccc}\bf{24\end{array}\right]$

So, from this begin understood, we would then combine both the penalties that were shotted, to the onces that weren't.

So, b subtracting these both, we would grab the result, and then smash that with the number of the penalties that were made in.

Your answer: $\boxed{\bf{76:24}}$
